Sentinel thoughts

I came across 20 amazing facts about the human body a couple of weeks ago. Some of the 20 I already knew, many I didn't. But the interesting ones from a Sentinel fandom perspective are 15, 16 and 20 on the list, as they deal with the senses.

(In case I have readers not in the fandom, the basic premise of The Sentinel is a genetic gift that enhances the five senses to an extraordinary/superhuman degree.)
